A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Is stable and has a user-friendly dashboard and a good interface
We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good We cannot secure a specific IP class with this firewall. Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the…

Though it helps deal with web traffic or any malicious traffic, it needs to work on its DC performance issues
The product's initial setup phase is moderate in level, so it is neither very complex nor very easy. For the deployment, my company first needs to gather all the requirements of the users and the domain names and consider how many users there are in the company. In the implementation and planning part, my company needs to consider what kind of policies we will create while ensuring that the policies are created based on the requirements of the users. There is a need to segregate the users' requirements since there are separate departments in the company, like the HR department, sales department, IT department, and manufacturing department, so that our company can create policies depending on their requirements. On-site, if you want a GRE tunnel, our company can handle GRE tunnel traffic routing and Zscaler Cloud Firewall, after which Zscaler will take action based on the policies created by our organization. For the deployments and maintenance, a team of five members consisting of two managers and three engineers is required.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Their interface is very easy to use, it is without bugs."
"This solution made it very easy to manage our bandwidth."
"Mainly the FortiGate reporting system is very good. It guides us through all the expectations of security. Fortinet provides us all that we need for security. Also, Fortinet FortiGate is a next-generation firewall. It is much more advanced than others."
"It's very good and very stable for businesses. It works very well."
"There are great templates, so you don't have to customize them if you don't want to. You do have the option to custom create some folders and some reports, however, with what is there, you don't really need to go through extra effort, as they already give you a lot of predefined views of reports and so forth."
"The most important feature, normally for small business customers, is link load balancing."
"Fortinet FortiGate has positively impacted our organization by allowing us to scale fast."
"SSL-VPN is very useful for us and has been very reliable."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"It has been stable so far."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"Once you have Zscaler running you have access to configure it however you want."
"The solution is scalable."
"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."
"Zscaler is still a very good product."
"Since it is really customizable, I can use it and avoid enabling access to the full network."
"Includes advanced tech protection."
"It is a stable solution."
"Zscaler provides effective protection against various cyber threats ensuring a safe environment"
 

Cons

"The firmware updates are sometimes not stable. The stability issues can vary, sometimes happening once a month or quarterly. New firmware updates can occasionally introduce bugs, causing some policies to fail. We then have to raise a ticket, and Fortinet usually provides a fix within a few days."
"They could do more work on FortiAnalyzer in terms of the data and the information coming from it."
"Areas that have room for improvement in Fortinet FortiGate include support and GUI enhancement."
"The AI with Fortinet FortiGate is not very well integrated on their devices, and their cloud infrastructure is not as good as Cisco's."
"For Fortinet FortiGate, their code development would definitely be something they need to improve on to reduce vulnerabilities that need to be patched."
"They should make the rule sets more understandable for the end user. When you're trying to explain to somebody how a computer network is secured, sometimes it's difficult for an end user or customer to understand. If there was a way to make the terminology more accessible to the end user, the set up could be easier. They should translate the technical jargon to an easily relatable and understandable conversation for the end user, the customer, that would be brilliant. Particularly in an environment where the IT structure is audited regularly, there's always pressure from the auditor to up the standards and up the security and you get your USCERT's that come out and there's a warning about this and the customer will want to lock out so much and when you apply it they run into issue where they can't search the internet or print to their remote office. Of course they can't print to your remote office, they just locked it up. They should make the language more understandable for the customer. If there's a product out there that made the jargon understandable to John Q. Public, I would buy that."
"The support costs and licensing are sometimes so expensive."
"The monitor and the visibility, in this proxy, is very weak."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Licensing is not cheap."
"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"We are having some issues with internet access being denied when organizational ID-based policies change. For example, a lower level employee ends up getting the same level of access as that of a higher level employee."
"I don't have the visibility of a control dashboard or a network management system."
"Data Leak Prevention is only for web filtering and there is no protection for email."
"If I can get rid of Jetscaler, I will use Twingate for sure."
"Its technical support services could be better."
"The product could improve its integration with some legacy systems."
"Certain criteria need to be met if you want to scale this solution."
"When it comes to customer support, there is room for improvement in Zscaler's service."
 

Pricing and Cost Advice

"The price for the Fortinet FortiGate is reasonable. Secure SD-WAN is free of charge. If you have their firewall, it's free of charge. It's very tempting."
"I think that the pricing is fair."
"It's very affordable."
"Other firewalls are more expensive than Fortinet FortiGate, such as the Azure firewall."
"The pricing of the solution is very competitive."
"The solution requires a license annually, it is not a user license, you can have as many users as your want. I must renew the license regularly per device."
"The pricing is flexible."
"It's very competitive."
"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
"We got a much cheaper price than that provided by Fortinet right now."
"The product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."
"It is not the most budget-friendly solution, but it's important to consider its overall value."
"There are licensing costs, and I would not say that it's a cheap vendor."
"There are different subscription models available."
"It comes at a significantly reduced cost while ensuring control and effectiveness."
"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."
"Zscaler is priced too high compared to the cost of Fortinet."
"There is an annual license required for the use of the Zscaler Cloud Firewall."
